Definitions

  • This invention relates generally to liquid droplet dental cleaners, and more specifically concerns a non-pressurized system for creating a droplet spray for dental cleaning.
  • Dental cleaners using a spray of liquid droplets to clean dental regions of the teeth, including interproximal areas, are known.
  • a stream of high velocity gas is used to create the liquid droplets when liquid is brought into contact with the gas stream, such as by a pump or other arrangement.
  • the high velocity gas stream uses compressed gas, such as from a cartridge source, to provide the energy necessary for the gas stream.
  • compressed gas such as from a cartridge source
  • a compressed gas appliance is generally effective to produce liquid droplets for cleaning.
  • compressed gas does have known limitations, including safety limitations and objections by some users to the taste of the resulting liquid droplets.
  • the depleted gas cartridges must also be disposed of safely and in an environmentally appropriate manner, which can be inconvenient.
  • liquid droplet dental appliance which is capable of producing liquid droplets for cleaning with a non-pressurized source of gas, in particular without the need for a compressed gas consumable cartridge.
  • the invention is a fluid droplet appliance for dental cleaning, comprising: a dental cleaning appliance having a body portion and a nozzle portion for exit of a spray of liquid droplets from a distal end thereof; a liquid reservoir wherein in operation liquid is moved from the reservoir into an area of the nozzle portion near an open proximal end thereof; a system for driving a piston element toward the proximal end of the nozzle portion with sufficient force that air acted on by the piston element is forced or released into the nozzle portion at a high rate of speed, sufficient to create a spray of liquid droplets when the moving air comes into contact with the liquid; and an orifice at the proximal end of the nozzle portion, through which air is forced by action of the piston element, wherein the system for moving the piston element includes a voice coil surrounding a magnet and a capacitor, wherein the magnet is connected to the piston element, and further including a source of power which charges the capacitor, wherein in operation the voice coil pulls the magnet to the rear of the appliance, away from the or
  • Appliances in which a piston element is used for acting on air to be used for contacting liquid and thereby creating a spray of liquid droplets are known from US 1,838,873 , US 5,997,518 and US 601,616 , for example.
  • US 1,838,873 relates to atomizing instruments of the type employed for applying a medicated liquid in a spray or finely atomized forin to the nose and throat.
  • US 5,997,518 discloses a device and method for delivering small microliter volumes of liquid preparations to the eye or other body part utilizing a gas stream to induce a controlled, preselected volume of liquid into the gas stream and to deliver the liquid in the form of small droplets to the desired site.
  • Figure 1 is a schematic view of an embodiment of a non-pressurized liquid droplet appliance.
  • Figure 1 shows a non-pressurized gas drive embodiment, generally referred to as a voice coil drive.
  • the appliance for creating a liquid droplet spray for dental cleaning is shown generally at 50. It includes a body portion 52 and a nozzle portion 54 which extends forwardly from the body portion. Body portion 52 includes an actuating element 72. Positioned within body portion 52 are a water reservoir 56 and a battery and circuit (electronics) portion 58. The battery and circuit portion 58 connects to a voice coil assembly 60, providing an energizing signal thereto.
  • the battery and circuit portion 58 includes a capacitor 62. Voice coil 60 encircles a magnet 64.
  • nozzle portion 54 Connected to magnet 64 and positioned between magnet 64 and the proximal end of nozzle portion 54 is a piston 66. At the proximal end 68 of nozzle portion 54, adjacent body portion 52, is a nozzle orifice 70. Orifice 70 is typically 0.5-10 mm in diameter.
  • the user operates button 72.
  • This energizes the voice coil 60, which pulls magnet 64 rearwardly, which in turn pulls piston 66 toward the rear of the appliance.
  • the piston is moved rearwardly, air moves into the interior of the body portion 52, either through orifice 70 or through a one-way valve in the body portion. The air could move into the interior of the appliance, or into a chamber within the appliance.
  • the capacitor 62 also begins to charge. When the charge reaches a certain preselected level the capacitor discharges into the voice coil which drives the magnet forward, pushing the piston toward the orifice.
  • the voice coil maintains the magnet and the piston in a rear position prior to operation of button 72.
  • the capacitor begins to charge, until it reaches a selected charge level, at which point the capacitor discharges into the voice coil, which drives the magnet and the piston forwardly.
  • Sufficient force is produced by the piston in each arrangement to force air at high speed through orifice 70.
  • the air forced through the orifice contacts liquid which is directed into the lower end of the nozzle through line 73 by means of a pump or the like.
  • Droplets are created by the interaction of the fast-moving air and the liquid.
  • the droplets created will vary in size. In this arrangement, the droplets will be, for instance, between 5 microns - 0.5 mm.
  • the gas stream will further help to move the droplets through the nozzle and out toward the teeth for cleaning.
  • the speed of the droplets can vary from relatively low speed, e.g. 10 meters per second, to a high speed of 200 meters per second or even greater. Typically, however, a 50 m/sec droplet velocity with droplets in the size range of 5 microns - 0.5 mm will provide effective dental cleaning.
